Note: microbial resistance of wool fabric treated with bis-Quats compounds.

In this paper, the antibacterial activity against Bacillus pumilus, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa of the wool fabrics treated with new antimicrobial bis-quaternary surfactants, DABK and DABB, is studied. The activity was established on the basis of the agar diffusion and protective antibacterial test results and on the basis of scanning electron microscopy (SEM) observation. The results were compared with the HTAB, a monoquaternary surfactant of conventional use. The results from the agar diffusion and protective antibacterial tests do not enable us to confirm whether these compounds are potentially useful antimicrobial agents for the protection of textiles. However, SEM observations show clearly the efficacy of these compounds to protect the wool fabrics against the micro-organisms. SEM has been a useful technique for the assessment of antibacterial activity in textiles.

[Clinical and urodynamic study of enuresis in a juvenile male population].

We carried out a clinical and urodynamic assay of 100 cases of enuresis of a male population of ages ranging from 17 to 25. 64% displayed urodynamic alterations and these were significantly greater (p less than 0.005) amongst those suffering from nocturnal enuresis with diurnal symptoms (90%) than amongst those suffering from nocturnal enuresis only (59%). 36% of the patients did not display any urodynamic alteration. The urodynamic dysfunction most commonly displayed was vesical instability (46%). The other urodynamic dysfunctions found were 18% of the total, and detrusor contraction alteration constituted 10% of these (2 of the cases corresponded to vesical-urethral neurogenic dysfunction). The presence of minimum latent rachichisis was accompanied by urodynamic alterations in a significantly larger proportion (p less than 0.005) than in individuals not displaying this. The three case of wide-scale rachischisis were accompanied by urodynamic alterations corresponding to vesico-urethral neurogenic dysfunction. The case of secondary enuresis displayed neither urodynamic nor radiological alterations. Juvenile age enuresis displayed similar characteristics to infantile enuresis, although the percentage of vesical instability was lower. However, detrusor contraction alterations increased and the presence of previously non diagnosed vesico-urethral neurogenic dysfunctions was displayed.
